Naabu on macos is looping to scan some IP addresses.Only the first 7 or 8 can scans can be successful. about naabu HOT 3 CLOSED

This is being worked on at #946 - Unfortunately there is some internal lock within gopacket that prevents a complete release of interface handlers. Additionally a few active handlers literally kill kernel performances in populating their ring buffers, making them unresponsive. So the internals are being reworked to create only one handler per interface and using a pool of workers with demultiplexed traffic. Until the PR is ready you can switch to connect scan where the kernel manages all connections independently via syscall:

...
ScanType:          "c",

Thanks for your answer. Thanks for your work.

Hi,
I am taking advantage of this issue which may explain my problem.

Additionally a few active handlers literally kill kernel performances in populating their ring buffers, making them unresponsive

Is it global to the use of the library? @Mzack9999
Here's my Go code :

package main

import (
	"log"

	"github.com/projectdiscovery/goflags"
	"github.com/projectdiscovery/naabu/v2/pkg/result"
	"github.com/projectdiscovery/naabu/v2/pkg/runner"
)

func main() {
	options := runner.Options{
		Host:      goflags.StringSlice{"domain.tld"},
		ScanType: "s",
		OnResult: func(hr *result.HostResult) {
			log.Println(hr.Host, hr.Ports)
		},
		TopPorts: "100",
		Threads: 25,
	}

	naabuRunner, _ := runner.NewRunner(&options)
	defer naabuRunner.Close()

	naabuRunner.RunEnumeration()
}

Performance is terrible compared to using the CLI :/

jomar@SRV:~$ time naabu -host domain.tld -tp 100 -silent
